DDJN R2020K Tungaloy turning insert — rhombic R2, 15° clearance

DDJNR2020K is an ISO-standard rhombic turning insert designed for external and internal turning applications, offering robust carbide performance for reliable chip control and repeatable results

• ISO-standard geometry for universal turning
• Carbide substrate for long tool life
• Rhombic R2 form for versatile facing and turning
• 15° clearance angle for secure cutting engagement

Consistent machining through ISO conformity and carbide durability

The ISO-standard design ensures interchangeability across matched toolholders and systems, reducing set-up time and inventory complexity. Manufactured from carbide, the insert delivers high wear resistance and predictable tool life in continuous production. This combination of standardised geometry and a wear-resistant substrate supports higher spindle utilisation and lower downtime, which translates into measurable process efficiency for precision turning tasks.

Secure seating and predictable cutting with rhombic geometry

The rhombic R2 form and 15° clearance angle provide a stable cutting geometry that improves engagement and supports a range of turning operations. With a plate thickness of 2.38 mm, the insert offers sufficient rigidity for both finishing and light roughing, while the absence of a central hole simplifies the clamping approach for certain holder types. Compatibility depends on holder shape, relief angle, tolerance class, fastening method, size and thickness; once matched correctly, the system delivers consistent cutting forces and surface finish.

Application guidance: selecting grade and system components

This ISO-series insert is intended for turning; select the appropriate chipbreaker and grade to match the workpiece material and machining conditions, since this variant is supplied without a chipbreaker. Typical system setup comprises the insert, a matching external holder or boring bar, a clamp or clamp set and replacement screws. For tasks requiring specific edge strength or coating, choose grades and coatings that balance surface finish and lifetime. If clarification is needed on grade selection or holder pairing, technical guidance is available to ensure optimal performance.
